    While it supports the most commonly used image formats, edge cases or niche formats may not be well supported, potentially requiring additional tools for full compatibility.
  • Potential Latency

  • Kindle to end store downloads and registering for 1st-5th gen kindles in May
    Calibre lets you put non-Amazon eBooks on these very same devices. It made me start using my old Kindle again: https://calibre-ebook.com/. - Source: Hacker News / 5 months ago
  • Your Old Kindle Isn't E-Waste: 3 DIY Projects to Give It a New Life [2026 Guide]
    Calibre is the open-source ebook management tool that's been around since 2006 and remains the gold standard. It converts between virtually every ebook format, manages metadata, and can push books to your Kindle over USB or wirelessly. - Source: dev.to / 5 months ago
  • anaconda on Xubuntu 24.04
    If I make the environment variable persistent in my .profile, Calibre's ebook reader does not work. - Source: dev.to / over 1 year ago
  • All Kindles can now be jailbroken
    I suspect most people that go this route (ie download and manage their own ebooks, then transfer them to their Kindle) use Calibre, which afaik, is unaffected by this change. https://calibre-ebook.com/. - Source: Hacker News / over 1 year ago
  • From RSS to My Kindle
    Very neat. I've been doing this with Calibre (https://calibre-ebook.com/), which involves plugging it into your PC via USB. Simple RSS feeds work with little configuration, and more complicated news sites require writing a custom python "recipe". This project uses Amazon's email gateway, which I think is limited to 25 articles per month (don't quote me on this). - Source: Hacker News / about 2 years ago

  • Ask HN: What are you working on? (June 2026)
    2. I finished adding image uploads. Now you can add and view image attachments.
       This was quite a challenging task because there are a lot of security implications, and Cloudflare Workers don't support sharp. So I was implementing all the pixel bomb detection, optimizations, and other stuff by myself. Also, [imgproxy](https://imgproxy.net) came in handy as a price-efficient image processing solution.
